I configured SDMMC1 as follows:hmmc1.Instance = SDMMC1; hmmc1.Init.ClockEdge = SDMMC_CLOCK_EDGE_RISING; hmmc1.Init.ClockPowerSave = SDMMC_CLOCK_POWER_SAVE_DISABLE; hmmc1.Init.BusWide = SDMMC_BUS_WIDE_8B; hmmc1.Init.HardwareFlowControl = SDMMC_HARDWAR...
hi,I have just implemented USB MSC device and file system in my stm32h743. it work properly, as I connect to PC it shows the device. my code logic is, i will write configuration file to file system and and controller will read that file. this is happ...
Hello there,I am newbie in CAN communication. Although there is no problem in loopback mode, I get acknowledgment error in normal mode. For this reason, the tx message I sent continues to be sent because it was not ACKed, and after a while, all mailb...
Hi,We try to implement a DRP device with the USBPD library on a STM32G071 uC.From the documentation the requirements for the following functions are not clear:BSP_USBPD_PWR_VBUSOff():- Should it block until VBUS < USBPD_PWR_LOW_VBUS_THRESHOLD?- What ...
We have custom bootloader that jumps to application when i switch off power and switch on power the bootloader dosent jump ton application , so again inned to upload Application to it
HelloI have a STM32F407VET6 with FreeRTOS continuously receiving data, normally 250-300 characters every 4[ms], by UART+DMA, when it receives a '\n' and idle-line sends the data received to a mailbox(8 mails length). Then a receiver task get one mail...
